Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 13,527,665, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 13,527,665 | |
| -1 | -13,527,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,527,665.
Example:
1 x 13,527,665 = 13,527,665
and
-1 x -13,527,665 = 13,527,665
Notice both answers equal 13,527,665
With that explanation out of the way, let's continue. Next, we take the number 13,527,665 and divide it by 2:
13,527,665 ÷ 2 = 6,763,832.5
If the quotient is a whole number, then 2 and 6,763,832.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,527,665 | |
| -1 | -13,527,665 |
Now, we try dividing 13,527,665 by 3:
13,527,665 ÷ 3 = 4,509,221.6667
If the quotient is a whole number, then 3 and 4,509,221.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,527,665 | |
| -1 | -13,527,665 |
Let's try dividing by 4:
13,527,665 ÷ 4 = 3,381,916.25
If the quotient is a whole number, then 4 and 3,381,916.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 13,527,665 | |
| -1 | 13,527,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 61 | 85 | 305 | 1,037 | 2,609 | 5,185 | 13,045 | 44,353 | 159,149 | 221,765 | 795,745 | 2,705,533 | 13,527,665 |
| -1 | -5 | -17 | -61 | -85 | -305 | -1,037 | -2,609 | -5,185 | -13,045 | -44,353 | -159,149 | -221,765 | -795,745 | -2,705,533 | -13,527,665 |
